El presente invento proporciona fluidos a base de enlaces cruzados de borato para el tratamiento de pozos, así como métodos de preparación y utilización de tales fluidos en le tratamiento de pozos, como podria ser la fragmentación de las zonas subterráneas encontradas en los mismos. Los fluidos de tratamiento a base de enlaces cruzados mejorados están básicamente comprendidos de agua, un agente coloide hidratado de galactomannan y una composición de borato para suavizar el fluido de tratamiento y que ocasiona un enlace cruzado del agente coloide hidratado de galactomannan comprendido por agua, una fuente de boro soluble y una álcolinalamina o alkilamina.The present invention provides fluids based on borate crosslinks for the treatment of wells, as well as methods of preparation and use of such fluids in the treatment of wells, such as the fragmentation of the underground zones found therein. The improved cross-link based treatment fluids are basically comprised of water, a hydrated galactomannan colloid agent and a borate composition to soften the treatment fluid and which causes a cross bond of the hydrolyzed galactomannan colloid agent, a a source of soluble boron and an alkoline or amine.
